fc' 10 all 'whom it may concern.'

Be it known that I, FRANK subject at New York, in the county of New York and State of New York, have invented new and useful Improvements in Twine or Cord Cutters, of which the following is a specilication.

This invention relates to improvements in twine or cord cutters wherein a supply of twine, in the form of a rolled ball, is supplied, the end being automatically advanced under the blade of a shear where it may be conveniently grasped. y

The principal object of ythe invention is to provide an apparatus which will perform the foregoing functions in a satisfactory manner. l i

Another Objectis to provide an apparatus of this nature which is readily portable, but adapted to rernainy stationary under ordinary circumstances when placed upon any convenient level surface, and finally, to provide an apparatus of this class which is cheap to construct, comprised of few and simple parts and not readily liable to become disarranged.

These and other KLINGA, a

objects are attained by the novel construction and combination of parts hereafter' described and shown 1n the accompanying drawing, forming a rnaterial part of this specification, and in which Figure 1 is a perspective view of a twine cutter, made in accordance with the invention, and Fig. 2 is an enlarged vertical section of the same.

The invention comprises a hollow base 10, provided with a metallic frame 11 engaged upon its upper surface from which rises a standard 12, supporting a hollow twine holder 13, containing a ball of twine 14, a single strand 15 passing outward through an appropriate opening formed in its lower wall.

An arm 18, turnably mounted on a pivot pin 19 within the base of the apparatus, eX- tends when erect, to a point abovethe surface of the frame 11, the arm having a transverse opening 20 through which the twine 15 passes, the arm also being formed with a horizontal central bore adapted to receive a plunger 22, having a curved upper surface 23 adapted to make contact with the twine 15 within the opening 20. The lower end of the plunger 22 extends rearofthe Kingv of Hungary, residingV wardly outward between the forked portions 24 of the arm 22, terminating in a curved end 25 engaged by the pin 26 with a lever 27, fulcrumed on the transverse pin 19 and having a depending lug 28 engaged Y byy a pin 29 with a curved link 30, the upper end of kwhich is connected by a pivot 31 with a bell-crank lever 33, fulcruined on a transverse rod 35 fastened similarly to the rod 19 within the hollow base of the apparat-us.

The bell-crank lever 33 has an oppositely disposed arm 36 to which is engaged one end of a coiled pull spring 38, the other end of the spring being secured to a stud 40 rigidly afHXed to the interior wall ofthe base 10, the same having a normal tendency to draw the parts hitherto enumerated into the position indicated by the broken lines. Also engaged with the arm 36 of the bellcrank lever by a pivotal connection 42, is a vertical link 43, the same extending upward to the shear plate 45 to which it is attached by the pin 4 6. The shear is transversely mounted over the surface of the apparatus and is pivotally secured to a lug 47 formed with the frame 11, by means of the pin 48; the opposite end of the shear 45, which operates in the manner of a lever, is provided with an operating knob 50 by means of which the shear may be depressed and brought into operative engagement with a fixed shear 52 secured to the side of a transverse bar 53 formed with the frame 11. On top of the bar 53 is a lug 54 containing an opening through which the cord passes closely adjacent to the shear 45 yto which is attached a projection 58, the same being bored vertically and containing a plunger 59, pressed normally downward by means of the coiled push spring 60, the reduced end 61 of the plunger extending downwardly through a cap 52 affixed to the lower end of the extension in such manner as to normally retain the plunger' and spring therein.

In operating the apparatus, pressure is applied to the knob 50, causing the shear to descend and cut off the cord. TWhen the pressure is released, the spring 38 raises the pivoted shear 45 and through the system of links and levers employed, presses the plunger 22 against the cord in the passage 20, formed in the arrn- 18, binding it firmly therein. When the plunger 22 has risen so far as the passage 20 will admit, the arm is caused to swing upon the pin 19, in the direction of the shear, causing the cord to advance thereunder, the plunger 61 being at that time raised. Furtherdepression oi' the knob 50 not only brings the parts to their initial position, but clamps the cord l5 between the bar 53 and the plunger 6l closely adjacent, through the opening in the lug 54, thus extending a length convenient for the operator to grasp in the further operation oi' the apparatus.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is r l. A device of the class described, com-y prising a hollow base, a `twine holder `secured thereon, a pivoted arm hingedly oonnected to said base, said arm being bored to admit the passage of twine therethrough, a fixed cutter blade, a hinged cutter blade cooperative therewith, a guide for the twine contiguous to said blades, means for clamping the twine adjacent to said guide when said hinged blade is depressed, means for raising said hinged blade, and means for projecting they cordlpast said hinged blade. 2. A device of the class described, comprising a hollow base, a twine holdeilsecured thereto, 'an oscillating arm having an opening through which the twine passes,

Copies 'of this patent may lne obtained for five' cents each, by addressing -the said base and extending thereabove, a hollow arm oscillatably mounted in said hollow basesaid arm having an opening through which the cord may pass, means for-gripping'the cord in said openings when said arm is caused to oscillate, a fixed blade, a twine guide ymounted thereon, a hinged blade, -means for depressing said hinged blade, means combined'with'said blade for clamping vtheoord contiguous to said cord guide,'means for raising 'said hinged blade and means cooperative therewith adapted to clamp lthe cord within said arm `and to cause said hollow 'arm .to oscillate y In `testimony whereof I have signed Vmy name to this specification.y
